Title: AN EFFICIENT APPROACH FOR DETERMINING INDUCTION MOTORS PARAMETERS
Keywords: genetic algorithms, induction motors, parameters of T-shaped equivalent circuit

Abstract: The paper presents an efficient approach for determining the equivalent circuit parameters of squirrel cage induction motors (IM) by genetic algorithms. A T80B4AB3 type squirrel cage induction motor is analyzed. The T-shaped equivalent circuit is utilized. There are five unknowns in the equivalent circuit. The known quantities from measurement are the input voltage, input current, power factor and slip. Genetic algorithms are used for determining the induction motor parameters. The results are compared by using one, two and three sets of measured data. The accuracy of the proposed approach is verified by determining the relative error in the parameters, obtained by genetic algorithms with regard to analytical values. It is shown that the presented approach needs only two points from the IM load curve. In contrast, the standard approach requires at least three points from the motor load curve to obtain relative error less than 1%.The reference contains 15 titles in the last years.
